<<The error is thrown on the line that try to get the domain of the computer. "Activeds.dll" is the dll that give that info>> suggestions not answers - Maybe start another thread titled "Is Activeds.dll supported" see if someone can answer that first. - If you can create a small test vb6 app yourself that just gets the domain of the computer (nothing else) and displays it in a window/msgbox. Test it on a real win box to confirm does as you expect and then maybe post the code on another thread specific to ActiveDS as current thread title is fairly generic.
